Precision tools for sourdough and pizza bakers.
Predict your starter's peak. Coach bulk fermentation. Plan a bake backwards from when you want to eat. See what makes your best bakes best.

Run a formula right now.
Five calculators from the app, free in your browser. Change an input and the formula updates as you go.
Three things most baking apps get wrong.
Know when your starter peaks.
Log a few feedings with the ambient temperature. A Q10 temperature model estimates when your next rise is likely to peak, and gets more useful as your history grows.
Less guessing. More signal.
Know when bulk is done. Not when the timer says.
Check the dough with a tap: volume %, jiggle, poke, ambient temp. Lievanto turns those readings into a live readiness estimate, so the dough can lead the schedule instead of the clock.
Temperature-aware, the whole way through.
Plan a bake backwards from when you want to eat.
Pick a target, say Saturday 6 pm, and Lievanto works back through feed, mix, bulk, cold proof, final proof, and bake. You can save the plan and add reminders when you need them.
It warns you if a step lands at 3 AM.
Real screens.





The more you bake, the more it knows.
The logbook
Every bake, tied to its recipe. Photos, ratings, and per-bake variables: hydration, ferment hours, flour, oven temp. Nothing forgotten between bakes.
Insights
The more you log, the more it notices. A 52-week histogram, a streak counter, rating-versus-variable correlations, and your top-rated recipes.
Cook mode
Guided step-by-step with timers and background notifications. Every step adapts to your kitchen, shown next to the original recipe, never silently replacing it.
Set up your kitchen
Tell Lievanto your oven and how you mix, once. Cook mode then tailors temperatures, timings, and instructions to the equipment you actually own.
Measure your way
Read and enter amounts in the units you think in: metric, imperial, or baker's percentages, or set the unit per ingredient. Temperatures in °C or °F.
The calculators
A full dough calculator with preferments, a DDT solver, a cold-ferment yeast calculator, pan-size, scaling, and production planning. Stable decimal math under the hood.
Troubleshoot guide
Walk a decision tree for a flat loaf, gummy crumb, or pale crust. Land on a diagnosis and concrete changes to try on the next bake.
Your data stays yours
Export your sessions to CSV. On iOS, kitchen temperature can prefill from local weather when enabled. No ads or advertising tracking.
Serious sourdough and pizza bakers.
If you've ever tried to remember whether the last bake was 75% hydration with a 20-hour cold proof, or 72% with 24, Lievanto is for you. It gathers the work that matters, and nothing that doesn't.
Opinions, stated up front.
Free early release
Everything in the app is free while we improve the workflow with early bakers. No subscription, no in-app purchases, no ads.
Numbers you can check
Baker's percentages, Q10 cold-ferment math, 0.01 g yeast precision. The web tools run the same formulas as the app, pinned by parity tests.
The original recipe is sacred
Equipment-aware suggestions adapt a recipe to your kitchen, shown next to the original, never instead of it.
Be first to know.
The iOS and Android apps are in their final proof. Leave your email and we'll send one message when they're live.
Even better: tell us what the app should do for you. Feature wishes from early bakers shape what we build next.
